A note on the use of the CEC L-33-A-93 test to predict the potential biodegradation of mineral oil based lubricants in soil

The biodegradabilities of five unformulated mineral oils (brightstock, 150 SN base oil, white oil and two gas oils) were determined in the CEC L-33-A-93 test and during 20 weeks incubation in nutrient-supplemented soil microcosms. Biodegradation in both studies was measured as the loss of extractabl...

Zusammenfassung:	The biodegradabilities of five unformulated mineral oils (brightstock, 150 SN base oil, white oil and two gas oils) were determined in the CEC L-33-A-93 test and during 20 weeks incubation in nutrient-supplemented soil microcosms. Biodegradation in both studies was measured as the loss of extractable hydrocarbon (‘primary’ biodegradation). There was a statistically significant ( P
